Calculating size and weight

When the shipment is too large?

Calculating volumetric weight

Large, lightweight packages are charged at their volumetric weight for the space they occupy, rather than their actual physical weight. To determine volumetric weight, first calculate the volume of your package and then multiply this figure by the relevant conversion factor.

Volumetric Calculation

How to calculate domestic volumetric (cubic) weight

For TNT Domestic Express services the standard volumetric calculation is based on 250 kg's per cubic metre. To calculate the volumetric weight for these types of shipments (chargeable weight) multiply the Length (L) x Width (W) x Height (H) in centimetres and divide by 4,000.
